The following is a walkthrough of the glitch in Pokémon Yellow version that allows you to catch Mew, without using Action Replay, Gameshark or other third party device. If done properly, following this procedure will result in an encounter with a level 7 Mew on Nugget Bridge.

Steps

  1. 1
    Defeat your rival on Nugget Bridge. His first Pokémon will be a Spearow of level 18, so it would be wise to have a Rock or Electric-type Pokémon as the first in your party. After this is completed, you must clear all of the trainers on Nugget Bridge, including the final man who offers you a position in Team Rocket.
  2. 2
    DO NOT battle the trainer hiding in the grass to the left of the bridge, as he will be a key part of the glitch later.

  3. 3
    Save the game, just in case!
  4. 4
    Start to work your way up towards where the other trainers are, battling each trainer and saving after each battle until you reach the trainer who has nothing but a level 17 Slowpoke.
  5. 5
    Do not fight him. Shut the game off and resume where you saved at the last trainer you fought (This is not part of the glitch, and if you already know which trainer not to fight you don't have to battle him and shut it off. The video link should help clarify this but if you are unable to access it you will find the saving technique useful).
  6. 6
    Find and capture an Abra (try looking in the grass just above the Day Care building). This is harder than one would think because it will teleport away from you on its first turn. It is hard to find, and throwing a Poke Ball on your first turn and crossing your fingers is basically your only option. However, once you've caught Abra you will be able to move on to the next step.
  7. 7
    Walk up Nugget Bridge and save when you reach the end. Now is the time to approach the trainer who is hiding in the grass, who you did not battle before.
  8. 8
    Walk in front of where he is, far enough away so that he cannot see you, but will see you if you take one step towards Cerulean. Save your game right here, because this next step can be tricky.
  9. 9
    Next hit the down arrow and the start button at the same time. You will take a step down toward the trainer, but the start menu will appear instead of the exclamation point above his head. Teleport back to the Pokémon Center with Abra, and walk back up Nugget Bridge. At this point your start menu will be disabled, but do not despair as this is part of the glitch.
  10. 10
    Fight the trainer with the level 17 Slowpoke, being sure to have him walk at least one step towards you to battle or the game will freeze.
  11. 11
    Defeat him, and teleport back to the Pokémon Center again. Then walk back up Nugget Bridge and your start menu will appear.
  12. 12
    Click the B button and a wild Mew will appear at level 7.
  13. 13
    Make sure to bring some Poke Balls, and good luck!

    The truck is just a myth. This is the easiest way to catch Mew and the earliest point it is possible to do so.
